In regards to Henderson, he is exactly what I pictured him to be when drafted. I've always maintained he was a supplementary, i.e. complementary RB to Gurley. The fan expectations for him were unrealistic. Stupid media seemed to think it herald the demise of Gurley. I will say it again he's not an every down RB. At this point, he's not even a 3rd down RB because he hasn't shown he can pass block. Right now Malcolm Brown is the 3rd down back because he can both catch, run the ball, but most of all he's the best pass blocking RB on the team. Brown simply lacks the breakaway speed to be a threat that Gurley is. Brown has basically average speed in the 4.6 range. He's a power runner and that is his role.
Henderson IMO is likely to play in a 2 RB set. I bet a lot of the time he will be lined up in the slot and run the jet sweep motion. As a receiver, he's a mismatch for LB's and even some SS. He's got good speed, but more importantly, when you watch his film it's his acceleration that stands out. He's a slashing type of RB who isn't as we have seen going to break tackles.
Bottom line is Henderson will be a very good offensive weapon when employed properly. Force defenses to account for him opening up other options for Goff and McVay.
The o-line rotation will sort itself out as the young guys gain experience. I think the offense might carry 7 WR's: Woods, Cooks, Kupp, Reynolds, Hodge, Thomas & Webster. Obviously, Webster will be primarily the designated returner. They can make room for that extra WR by simply not carrying a 3rd TE who never plays anyway. If it ever came to that, Josh Reynolds can line up in the TE position. As I've pointed out previously, the TE's run the Y (slot receiver) route tree so he knows that already.
It's very rare that Ram TE's perform inline blocking. Most are of the chip variety. That's why I'm saying this team doesn't need to carry 3 TE's. An extra WR is far more valuable. Also, why release a WR to be picked up by AZ or SF?
Bottom line I came away from that game saying to myself that this team is ready for a SB run because it is deep all over the roster.
